Mouse Response

• Vaccination Protocol: Intranasal vaccination with RBD-rAAV (Zheng et al., 2008).
• Vaccine Immune Response Type: VO_0000287
• Challenge Protocol: Mice were challenged with 10⁵ TCID50f SARS-CoV strain GZ50 (Zheng et al., 2008).
• Efficacy: RBD-rAAV vaccination provoked a prolonged antibody response with continually increasing levels of neutralising activity. When compared with the RBD-rAAV prime/boost vaccination, RBD-rAAV prime/RBD-peptide boost induced similar levels of Th1 and neutralising antibody responses that protected vaccinated mice from subsequent SARS-CoV challenges,but stronger Th2 and CTL responses (Zheng et al., 2008).

Mouse Response

• Vaccination Protocol: Mice were separated into 4 groups (9 mice per group) and primed with RBD-rAAV [intramuscular (i.m.), 2 × 10¹¹ VP /200 μl)] or RBD-peptides (N50 and N60, 50 μg each) plus CpG ODN (25 μg) [subcutaneous, (s.c.)] or blank AAV, and boosted with RBD-rAAV or RBD-Pep or AAV, respectively (Du et al., 2008).
• Vaccine Immune Response Type: VO_0003057
• Challenge Protocol: Forty days post-vaccination, mice were anaesthetized with isoflurane and i.n. inoculated with 50 μl of SARS-CoV strain GZ50 (5 × 10⁵ TCID50) (Du et al., 2008).
• Efficacy: Compared with the RBD-rAAV prime/boost vaccination, RBD-rAAV prime/RBD-peptide (RBD-Pep) boost induced similar levels of Th1 and neutralizing antibody responses that protected the vaccinated mice from subsequent SARS-CoV challenge, but stronger Th2 and CTL responses. No significant immune responses and protective effects were detected in mice vaccinated with RBD-Pep or blank AAV alone (Du et al., 2008).

Mouse Response

• Vaccination Protocol: Mice were immunized with two intraperitoneal (i.p.) injections at 4-week interval of 10⁵ TCID50 of MV-S or MV-Ssol recombinant viruses (Escriou et al., 2014).
• Vaccine Immune Response Type: VO_0003057
• Challenge Protocol: Mice were inoculated intranasally with 105 pfu of SARS-CoV five weeks after the second immunization (Escriou et al., 2014).
• Efficacy: Recombinant MV expressing the anchored full-length S induced the highest titers of neutralizing antibodies and fully protected immunized animals from intranasal infectious challenge with SARS-CoV (Escriou et al., 2014).

Mouse Response

• Host Strain: BALB/c
• Vaccination Protocol: Mice were Mice were separated into 4 groups (9 mice per group) and primed with RBD-rAAV [intramuscular (i.m.), 2 × 10¹¹ VP /200 μl)] or RBD-peptides (N50 and N60, 50 μg each) plus CpG ODN (25 μg) [subcutaneous, (s.c.)] or blank AAV, and boosted with RBD-rAAV or RBD-Pep or AAV, respectively (Du et al., 2008).
• Challenge Protocol: Mice intranasally challenged with SARS-CoV strain GZ50 40 days post-vaccination (Du et al., 2008).
• Efficacy: SARS-CoV viral load in lung tissues was significantly reduced in mice vaccinated with RBD-Pep. Very low level of viral load was detected in lung tissues of RBD-rAAV prime/RBD-Pep boost group, similar to that in lung tissues of RBD-rAAV prime/RBD-rAAV boost group. Vaccination of RBD-rAAV prime/RBD-peptide boost was able to significantly inhibit SARS-CoV infection (Du et al., 2008).
